Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
182 words
A method of continuous manufacture of shielded electrical cable suitable for use in hot environments, comprising positioning at least two continuous electrical conductor means spaced apart from each other, advancing said at least two electrical conductor means from a starting position through a given region lying generally forwardly and axially of the starting position while maintaining the spaced apart relationship, simultaneously moving a continuous length of said wire into said region, advancing a continuous strip of flat metal material past tube forming means so as to form a continuous tube therefrom in a position surrounding said given region, while concurrently depositing a sufficient amount of fluent ceramic insulating material on at least a portion of said strip for enclosure thereof within said tube to fill said tube as said tube is formed, and thereafter advancing said tube, said insulation contained therein and said conductors through means for reducing the diameter of said tube and applying tension to said two conductors thereby maintaining the spaced apart conditions to compact said insulation and permanently position said two conductors therein in the spaced apart condition.
Claim 2
Independent Claim
182 words
A method of continuous manufacture of shielded electrical cable suitable for use in hot environments, comprising positioning at least two continuous electrical conductor means spaced apart from each other, advancing said at least two electrical conductor means from a starting position through a given region lying generally forwardly and axially of the starting position while maintaining the spaced apart relationship, simultaneously moving a continuous length of said wire into said region, advancing a continuous strip of flat metal material past tube forming means so as to form a continuous tube therefrom in a position surrounding said given region, while concurrently depositing a sufficient amount of fluent ceramic insulating material on at least a portion of said strip for enclosure thereof within said tube to fill said tube as said tube is formed, and thereafter advancing said tube, said insulation contained therein and said conductors through means for reducing the diameter of said tube and applying tension to said two conductors thereby maintaining the spaced apart conditions to compact said insulation and permanently position said two conductors therein in the spaced apart condition.
Claim 3
Dependent Claim
24 words
A method as defined in claim 1 in which said strip material is continuously cleaned immediately prior to deposition thereof of said insulating material.
Claim 4
Dependent Claim
25 words
A method as defined in claim 1 in which said conductor means are cleaned immediately prior to being positioned for inclusion within said shielded conductor.
Claim 5
Dependent Claim
34 words
A method as defined in claim 1 in which said tube forming means includes a plurality of sets of hourglass rollers and welding means for permanently joining adjacent edges of said flat material together.
Claim 6
Dependent Claim
20 words
A method as defined in claim 1 in which said fluent insulating material comprises a finely subdivided metallic oxide material.
Claim 7
Dependent Claim
20 words
A method as defined in claim 1 in which said conductor means comprises two electrically conductive wires or differing composition.
Claim 8
Dependent Claim
34 words
A method as defined in claim 1 in which said conductor means comprises two wires of differing compositions said wires being adapted, when joined at their adjacent end portions, to form a thermocouple junction.
Claim 9
Dependent Claim
16 words
A method as defined in claim 1 in which said flat metal material comprises stainless steel.
Claim 10
Dependent Claim
21 words
A method as defined in claim 1 in which said electrical conductor means comprises at least one electrical resistance heating element.
Claim 11
Dependent Claim
21 words
A method as defined in claim 2 in which said cleaning is accomplished by application of ultrasonic energy to said strip.
Claim 12
Dependent Claim
22 words
A method as defined in claim 3 in which said cleaning is accomplished by application of ultrasonic energy to said conductor means.
